Palmer was granted the rare honour of
lying in rest in the
Chapel of St Mary Undercroft, Palace of Westminster; other recipients of this honour include: the former
Prime Minister Margaret Thatcher in 2013 and the former
Postmaster General Tony Benn in 2014. On 9 April 2017, his coffin was received into the chapel with a guard of honour of police officers. A private service was then held for his family. The following day, on 10 April, Palmer's coffin travelled in procession to
Southwark Cathedral, escorted by motorcycle outriders from the Special Escort Group of the Metropolitan Police. The route was long and avoided
Westminster Bridge where the terrorist attack had begun. Instead, the procession crossed the Thames over
Lambeth Bridge, during which a ten-second horn salute was given by boats on the river. Tens of thousands of people lined the streets, including 5,000 police officers. The procession was fronted by a colour party carrying the Metropolitan Police Service Standard, who were followed by five mounted police officers. Then came the funeral conductor and chaplains (including
Rose Hudson-Wilkin,
Chaplain to the Speaker of the House of Commons) who were walking in front of the
hearse. The hearse carried Palmer's coffin which was draped in the police flag, and there were "red and white floral tributes atop the hearse"; these "spelled out 'No 1 Daddy', 'husband', 'son', 'brother', 'uncle' and 'Keith'". Making up the rear were cars carrying his family, and four more mounted officers. Palmer was given a full police funeral at Southwark Cathedral. It was attended by his family and friends, and a number of dignitaries including
Cressida Dick, the newly appointed Commissioner of the Metropolitan Police. Dick read the poem "
Funeral Blues" by
W. H. Auden at the service which was her first public engagement since taking up the post. The address was given by
Andrew Nunn, the Dean of Southwark. ==Personal life==
